You buy something on Amazon. Takes 90 seconds, maybe less. One-click checkout, product shows up tomorrow. You barely thought about it.
Behind the scenes, your purchase was far from simple.
Amazon looked at your IP address and knew what town you were ordering from. They checked their fulfillment network and saw three distribution centers within 50 miles. Inventory levels were solid. They scanned your purchase history: you’re a Prime member. You’ve ordered 47 times in the last year, average order value $83, and you abandon cart 8% of the time when shipping costs more than $6.99. They served you free next-day delivery because their model said you’d convert at 91% with that offer versus 67% without it. They showed you a specific checkout page- not just any checkout page, your checkout page, architected in real-time based on thousands of data points.
Oh yeah, and they tempted you with those sunglasses you’ve been considering, now discounted.
They also incentivized you to opt in to their credit card with strong cash back rewards.
They dangled a discounted expedited shipping option in front of you. It can be yours in 24 hours for an extra $3.99 (typically $12.99).
You saw one button. They ran a thousand calculations as the checkout page was loading.
That’s the gap. That’s what separates Amazon from nearly everyone else in e-commerce. That gap is worth billions.
What are other merchants doing?
I’ve been talking to the e-commerce execs who run checkout for some of the biggest brands in the world. Amazon, Alibaba, eBay, Etsy, Target, Walmart, Petco, Macy’s, Procter & Gamble, Anheuser-Busch, Nestlé. I’ve talked to all of them, and here’s what I learned:
Most retailers run the same checkout for every single person.
A first-time visitor from rural Montana sees the same shipping options as a repeat customer in Manhattan. Someone buying $300 worth of stuff gets the same free shipping threshold as someone buying $35. A logged-in loyalty member goes through the same friction as a guest who’s never heard of your brand.
I spoke with a senior product manager at a major retailer who said it plainly: they A/B tested hiding expedited shipping options to reduce cognitive load. Conversion went up slightly. But the lift didn’t offset the revenue they lost from people who would’ve paid for faster delivery. They killed the test.
Why? Because they were optimizing checkout as a monolith instead of as a dynamic system. They treated all customers the same, did not personalize, and treated it as a “one-off” experiment. What if they could have both? Simple shipping options for some? Expedited for others?
What if they could dynamically evaluate what shoppers value when ordering in the middle of the week? Versus the weekend? Or maybe based on the item? You may be willing to pay for expedited shipping when ordering garbage bags or laundry detergent. But that bathing suit ordered in the dead of winter? Perhaps not.
I spoke with a high-growth men’s grooming brand, doing $20M+ in revenue through both DTC and Amazon. They run on BigCommerce with a headless checkout. It took them six weeks to build a progress bar. Just a progress bar! Then another few weeks to test it. By the time they launched a basic feature, they’d burned two or three months. Meanwhile, their checkout was static. Same experience whether you were buying your first razor or your fifteenth refill.
They’re moving to Shopify next year because they finally realized: speed and agility matter more than custom control when you’re under $50M in revenue. But even on Shopify, they’ll face the same problem if they don’t have the infrastructure to learn from every checkout, fine-tune, and re-optimize.
It’s not their fault. The tools created for merchants were built with rigidity on purpose. Load your shipping options, take a payment, log the order. What I found interesting through these conversations was the complete lack of innovation and dynamism when it comes to managing checkout.
The $2 Trillion Opportunity
Here’s a stat that should wake e-commerce brands up: brands that offer personalization will capture $2 trillion in incremental value over the next five years. That’s from Mark Abraham, an author and senior executive at the Boston Consulting Group. Check out his TED Talk.
That’s $2 TRILLION. Not from better products. Not from better ads. Nothing is changing other than showing the right experience to the right person at the right time. That’s a big value unlock available to all online merchants if they can equip themselves with the tools to access it.
Personalization is not a new concept in software. At PeakSpan we have invested in several personalization vendors, including Maxymiser (site personalization), Cordial (email personalization), GroupBy (personalized search), and Stylitics (fashion and apparel personalization).
After years of research, we still see a gap in personalization vendors when it comes to checkout. This is a shame given that checkout is the highest-leverage node in the shopper journey. It’s the last mile. The moment of truth. The difference between 2.3% conversion and 3.8% conversion. At scale, this is the difference between a decent year and a major inflection point.
Amazon knows this. So do Target, Walmart, Netflix, and Uber. They don’t treat checkout like a static form. They treat it like a living, breathing organism that gets smarter every day.
They don’t have one person tasked with checkout personalization, they have massive teams. They invest tens of millions of dollars. Why? Because it’s THAT important and impactful.
Other brands? They treat checkout like a set-it-and-forget-it utility. And they’re leaving significant value on the table.
What “Good” Actually Looks Like
Let me paint the picture.
The best-performing e-commerce brands maintain a centralized repository of checkout and shopper data. Not just “conversion rate” and “revenue.” I’m talking about:
They analyze this data constantly. They run experiments continuously. They fine-tune checkout like a mad scientist tweaking variables in a lab. And they are reaping the rewards.

They don’t just “optimize” checkout once a quarter. They automate the optimization. The system learns. The system adapts. The system gets better without human intervention. It’s autonomous.
The Autonomous Checkout Era
Here’s the bottom line: even if you’re doing something unique at checkout, it’s not enough.
You can’t just run a test once a month and call it optimization. You can’t rely on your dev team to implement a new feature every quarter. You can’t house your checkout data across five different tools that don’t talk to each other. You need a centralized system of intelligence, context, and action. You need to deliver the right checkout experience to the right customer at the exact right time.
In speaking with these brands, I was quite interested in the tooling and infrastructure being used to manage and optimize checkout experience on an ongoing basis. Outside of merchants who live double lives as technology companies (Amazon, Etsy, etc.), I got zero good answers. Crickets.
The brands that win will be the ones that make checkout autonomous. The ones that build systems, or use platforms, that continuously test, learn, and improve without waiting for someone to manually change a line of code.
Depending on the size of the brand, this could mean tens of millions in incremental revenue per year. For Amazon? Billions. It’s worth a significant investment.
The gap between “we optimized checkout last quarter” and “our checkout optimizes itself every day” is the gap between good and great. Between survival and dominance in the next era of personalized customer experience. As Mark from BCG shared, there is $2TN in value there for the taking.
Enter PrettyDamnQuick
This is where I should probably tell you: PeakSpan is an investor in a company called PrettyDamnQuick (PDQ for short). Our personalization research paid off and we found the one player attacking checkout personalization with enough depth to drive real, durable impact across the industry.
And so, please take this with whatever grain of salt you need. But here’s why we invested:
PDQ is the only platform we’ve seen that actually solves this problem end-to-end, autonomously:
It’s not just A/B testing software. It’s not just a Shopify app that adds a progress bar. It’s infrastructure for autonomous checkout. PDQ is not software, it’s a data infrastructure and applied AI platform.
PDQ becomes the autonomous intelligence layer that empowers checkout for e-commerce. This infrastructure can think, decide, and act — making every checkout smarter and more profitable. What’s more, in working with hundreds of similar brands, PrettyDamnQuick has accumulated broad-scale intelligence on e-commerce checkout. Every merchant benefits from the collective intelligence of the entire network.
Most brands don’t have the resources to build this themselves. Even if they did, it would take years and millions of dollars. PDQ gives you the scaffolding to start acting like Amazon (without needing Amazon’s engineering team).
If you’re doing $10M+ in e-commerce revenue and you’re not treating checkout as a dynamic, data-driven system, you’re leaving money on the table. Probably a lot of it.
The future of checkout isn’t manual. It’s not static. It’s autonomous.
And the brands that figure this out first are going to eat everyone else’s lunch. Pretty damn quickly.
